I am a loyal player of Mount & Blade, and after seeing the addition of a weather system in Mount & Blade II: Bannerlord, I would like to offer some suggestions to make it more complete:
1. The desert area should randomly generate sandstorms, similar to foggy weather, which would reduce visibility during battles.
2. In snowy weather, riding a horse on snow should reduce speed, and on ice, it should reduce maneuverability, making it difficult to turn and slow down.
3. In rainy weather, thunder could be used to add excitement to battles. During combat with enemies, when lightning strikes, there should be a chance that the collision of bladed weapons causes an electric shock, resulting in damage.
The most tedious part of the current gameplay is the high level of repetition. I hope my suggestions will be seen by the developers. Enhancing the weather system would greatly increase the playability of battles in the game.
